Elevation, Temperature and more importantly Altitude Density all make a differance in a loads efficiency as well as the bullets BC its in a constant mode of change. Same range different day and a change in the above will yeild different results on the Target. That is why one should always try to keep his load in tune, more so with the small capacity cases. Its not untypical for the jacketed bullet bench rest shooters to make small changes in their tune from one relay to the next based on the changes of the above mentioned. The larger capacity cases such as the 32-40 for Schuetzen bench work use seem to be less sensitive / more forgiving to those changes due to the increased air space. A small powder charge increase in a small capacity case can push one over the pressure limits but the same change will have little effect in a 32-40.

Hi,

You're correct.  I think mine is the sole surviving .32-20 CPA in the area.  And yes, it's been in the safe for several years.

I've never owned any breech-seating rifle that could match the performance of  that particular .32-20 CPA.  The problem is that it requires a lot of time and effort to produce the loads that allow the rifle to achieve it's potential and, I'm no longer willing to put in the hours.

So, even though I no longer use the rifle, it remains a benchmark for exposed-hammer rifles - rechambering is out of the question.
